Keyboard device

Abstract

Disclosed is a keyboard device, in which a plurality of keys 3 are attached to a keyboard chassis 1 rotatably in a keying direction. In the keyboard device 100, a key pressing member 20 of the keyboard chassis 1 includes sliding portions 26 as protruding parts. Chassis attachment portions 36 of the keys 3 include opening portions 36a as recessed parts. A configuration is adopted so that, in a state where the sliding portions 26 and the opening portions 36a are engaged with other, the keys 3 can be prevented from dropping off from the keyboard chassis 1, and inclination of the keys 3 in a transverse direction can be suppressed.

[0001] CROSS REFERENCE TO RELATED APPLICATIONS: This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2010-148828, filed June 30, 2010, the entire contents of which are incorporated herein by reference middle. technical field [0002] The invention relates to a keyboard device. Background technique [0003] The keyboard device of an electronic musical instrument such as an electronic piano generally has a keyboard chassis and a plurality of keys (white keys and black keys). The end portion fits into the mounting portion, whereby the key is mounted so as to be rotatable in the up and down direction.

Problems solved by technology

[0007] However, as described in Japanese Patent Application Laid-Open No. 5-165460, in the case of pressing only the rear end of the key from above with the pressing plate, when the key is pressed strongly, the smooth movement of the key will be hindered.

On the other hand, when only lightly pressed, when a strong impact is applied, it is not possible to sufficiently prevent the key from being lifted or dropped, or to prevent the key from being tilted or shaken laterally.
